Fritz Klug / Kalamazoo GazettePolice cars were parked outside a house on the 400 block of Garfield Avenue in Kalamazoo investigating after a 10-day-old baby boy was apparently mauled by the family's pitbull.

KALAMAZOO — A 10-day-old baby boy died Saturday after sustaining injuries from a pit-bull attack, according to the Kalamazoo Department of Public Safety.

Police said in a press release that it appeared the Kalamazoo infant had been mauled by the family's pit bull terrier. The baby suffered extensive trauma, officers said, and he was pronounced dead at the scene.

Officers said they received a call at around 4:30 p.m. about a medical emergency at a residence in the 400 block of Garfield Avenue, located on the city's south side.

Officers did not release the name of the baby or his family members late Saturday, pending investigation.

Officers said the victim's mother and a 2-year-old sibling were in the residence at the time of the incident. The dog was removed from the residence and quarantined, officers said.

Four hours after the incident, at about 8:30 p.m. Saturday, many of the lights were on inside the single-story Garfield Avenue residence, located in an middle-class area of Kalamazoo, just from South Westnedge Avenue.

Window blinds were drawn and officers said police were the only ones inside the house.

Note: An earlier version of this story identified the baby as 10 months old. He was 10 days old.
